Duplaisir had earlier this year pleaded guilty to interstate transmission of extortionate communication.

Authorities say Duplaisir lured James Arnt Aune into a sexually explicit online relationship by pretending to be an underage girl. Later, Duplaisir pretended to be the girl’s outraged father, and demanded money to keep the relationship secret.

Aune jumped to his death from a campus building in January. Court records show text messages between Duplaisir and the 59-year-old Aune indicate the threats to publicize the relationship contributed to the communication professor’s decision to commit suicide.
